Abstract: According to the invention, a system for presenting graphics on a display device is disclosed. The system may include an eye tracking device, at least one processor, and a graphics processing device. The eye tracking device may be for determining at least one of a gaze point of a user on a display device, or a change in the gaze point of the user on the display device. The processor may be for receiving data from the eye tracking device and modifying use of at least one system resource based at least in part on the data received from the eye tracking device. The graphics processing device may be for causing an image to be displayed on the display device.

Abstract: The present invention provides improved methods and systems for assisting a user when interacting with a graphical user interface by combining gaze based input with gesture based user commands. The present invention provide systems, devices and method that enable a user of a computer system without a traditional touch-screen to interact with graphical user interfaces in a touch-screen like manner using a combination of gaze based input and gesture based user commands. Furthermore, the present invention offers a solution for touch-screen like interaction using gaze input and gesture based input as a complement or an alternative to touch-screen interactions with a computer device having a touch-screen, such as for instance in situations where interaction with the regular touch-screen is cumbersome or ergonomically challenging. Further, the present invention provides systems, devices and methods for combined gaze and gesture based interaction with graphical user interfaces to achieve a touchscreen like environment in computer systems without a traditional touchscreen or in computer systems having a touchscreen arranged ergonomically unfavourable for the user or a touchscreen arranged such that it is more comfortable for the user to use gesture and gaze for the interaction than the touchscreen.

Abstract: A gaze tracking system, leaving a low power mode in response to an activation signal, initial burst of eye pictures in short time by restricting the image area of a sensor, purpose of enabling an increased frame rate. Subsequent eye pictures are captured at le rate. The first gaze point value is computed memorylessly based on the initial burst res and no additional imagery, while subsequent values may be computed recursively to account previous gaze point values or information from previous eye pictures. The restriction of the image area may be guided by a preliminary overview picture captured using the different sensor. From the gaze point values, the system may derive a control signal to a computer device with a visual display.

Abstract: According to the invention, a method for changing the behavior of computer program elements is disclosed. The method may include determining, with an eye tracking device, a gaze point of a user. The method may also include causing, with a computer system, an interactive event controlled by the computer system to alter its behavior based at least in part on the gaze point of the user.

Abstract: A system is disclosed which may include an eye tracking device and a processor. The eye tracking device may be for determining a gaze direction of a user. The processor may be configured to cause a first image to be displayed on a display device. The processor may also be configured to determine a velocity of a saccade by a user based at least in part on the gaze direction. The processor may further be configured to modify the first image to generate a second image based at least in part on the velocity of the saccade. Modifying the first image may include altering an image quality of an area of the first image, and the area may be selected based at least in part on the velocity of the saccade.

Abstract: A method for panning content on a display of a wearable device is disclosed. The method may include determining, via an eye tracking device, a gaze direction of a user. The method may also include determining, via a movement detection system, a head direction of the user. The method may further include, based at least in part on the gaze direction and the head direction both being consistent with a particular direction, causing content displayed on a display of the wearable device to be panned in the particular direction. The method may additionally include determining during panning of the content, via the eye tracking device, that the gaze direction of the user has returned to a neutral position. The method may moreover include, based at least in part on the gaze direction of the user returning to the neutral position, causing content displayed on the display to stop panning.

Abstract: A computer system can be controlled with non-contact inputs through zonal control. In an embodiment, a non-contact input that is an eye-tracking device is used to track the gaze of a user. A computer's display, and beyond, can be separated into a number of discrete zones according to a configuration. Each zone is associated with a computer function. The zones and/or their functions can, but need not, be indicated to the user. The user can perform the various functions by moving gaze towards the zone associated with that function and providing an activation signal of intent. The activation signal of intent can be a contact-required or non-contact action, such as a button press or dwelling gaze, respectively.
